Good comment but for me this goes deeper. Somewhere on very basic existential level, people are either content with who they are, or they are not. Those they are need to be in properly miserable place to feel long term bad about themselves, and those who aren't are exact opposite - they can't reach proper long-term happiness no matter how much they achieve.

Tons of people that are ridiculously successful and achieved a lot on the outside are deeply dissatisfied inside, and so far I haven't heard about a single case where this can be really fixed and they can just sit back and enjoy the life (for more than a passing moment). I would feel bad about those unfortunate souls with this constant drive, but that would require ignoring much worse things in this world.

So thank you all of you crazy overachievers. And go take a break and enjoy the sun and the breeze for a moment.
